/ Specification of Letters Patent.

Patented July 20, 1915.

Application filed November 1, 1912. Serial No. 729,003.

To all whom it may concern:

Be it known that I, Howano M. BARBER,

a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invent ed a new and useful Improvement in Sheet- Delivery. Mechanism for Printing-Presses, of which the following is a specification.

The object of my invention is to provide a novel and efficient means for delivering alternate sheets, cut from a web, in separate piles, and more specifically to means for delivering single sheets, as they are cut from the main web, two at each revolution of the printing press, in two separate piles.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents the mechanism partly in end elevation and partly in section, Fig. 2 is a view of the mechanism in side elevation, Fig. 3 is av detail section showing the cam mechanism for controlling the operation of the grippers on the delivery cylinders, and Fig. 4 is a longitudinal vertical section through the mechanism. 7

The web feeding cylinder is denoted by 1. Means are provided for transversely cutting sheets from the main web, which means is herein shown as a pair of coacting rotary cutters 2, 3.

The two delivery cylinders are denoted by 1, 5, and their grippers by 6, 7, which grippers are arranged to alternately deliver the sheets cut from the main web. Guides 8, 9, are provided for guiding the web from the rotary cutters to the delivery cylinders. The side chains 10 of each of two endless delivery carriers pass around out-er pulleys 11 mounted on suitable stud axles 12 and at their inner ends around pulleys 13, mounted on bearings 14 eccentric to the shafts 15 of the delivery cylinders 4 and The side chains 10 pass along guides 16. Each of these endless delivery carriers is provided with one or more sets of grippers 18 arranged to engage the'side edges of the sheet near its advance edge. In the proportion of the parts herein shown. two sets of these grippers are provided on each of the delivery carriers. The eccentric mounting of the innerpulleys 13 permits the inner ends of the side chains to travel within the peripheries of the delivery cylinders 4. and 5 until the bottoms of the delivery cylinders are reached where the sheets are transferred from the delivery cylinder grippers to the endless delivery carrier grippers. I I

The two sheet receiving tables are denoted by 19 and 20, which tables are arranged beneath the twoendlessi delivery carriers in position to receive the sheets therefrom. These endless delivery carriers are driven at the surface speed of the delivery cylinders and their grippers are so arranged that the sheets are taken alternately and delivered onto the tables 19 and 20.

A retarding mechanism is provided for reducing the speed of the sheets as they are delivered to insure the proper delivery of the sheets onto the tables 19 and 20, which re tarding mechanism comprises members carried by the delivery cylinders opposite their grippers, and coacting members carried by the frame. Each of the cylinder members comprises aseries of spring pressed arms 21, the free ends of which arms are preferably provided with rollers 22, and each of the coacting members coinprises'a series of spring pressed shoes 28 carried by a rocking lever 21. These two rocking levers 21 are connected to move together by a rod 25 and" a. common rock lever 26 having a. crank and pitman connection 27, 28, with the shaft of one ofthe delivery cylinders, in the present instance the delivery cylinder 4:. Fixed cams 29, 30, have. respectively, cam surfaces 31, 32, for engaging their respective arms to open the grippers 6, 7, to receive the advance edge of the web. These cams 29 and 30 are also provided, respectively, with cam surfaces 33, 31, for opening the'grippers to transfer the control of the sheets from said gr ppers to the corresponding grippers on the endless delivery carriers at the proper times.

Flxed cams are arranged in pairs at the inner end of each endless delivery carrier and are provided with cam surfaces 36 arranged to engage the arms of the endless delivery carrier grippers for opening the grippers at the proper time to receive the advance side edges of the sheets and close upon the same to take the control of said sheets from the delivery cylinder grippers.

A pair of fixed cams 37 is arranged at the outer end of each of the endless delivery car-- riers and the said cams are provided with surfaces 38 arranged to engage the arms of the endless delivery carrier grippers at the proper time for releasing the sheets to deliver them onto the sheet receiving table A fixed cam 39 is provided for each set of rocking arms 21, said cams being arranged to rock the said arms outwardly into coaction with the shoes 23 for clamping the rear portion of the sheets being delivered between them, a sufficient time to reduce the speed of the sheet before it drops onto its receiving table.

The movement of the shoes 23 is slower than the movement of the delivery cylinder and endless delivery carriers. As the rocking arms are carried by the delivery cylinders, their rollers 22 will roll along the sheet held between them and the shoes 23 while still clamping the sheet to the shoes 23 for reducing the speed of the sheets. The delivery cylinders are driven at the speed of the press through the gears 40, 41, 42, 43, 25 so that each cylinder delivers a single sheet at each revolution of the press. The rotary cutters 2 and 3 are driven at the proper speed through the gears 42, 45, 46, to out two sheets from the web for every revolution of the press. The feed cylinder 1 is driven at the proper speed through the gears 48, 49, 50, 51. The endless delivery carriers ,are driven at the surface speed of the delivery cylinders through gears 52, 53, on the shafts 54, 55, of the gears 44, 45, which gears 52, 53, mesh with the teeth on the side chains of the said dlivery carriers.

The operation of the delivery mechanism is as follows :The web passes around the feed cylinder 1 and downwardly through the cutters 2, 3, guides 8, 9, to the delivery cylinders 4, 5. The grippers on one of these cylinders engage the advance edge of the web at the point a: and as the grippers 6 reach the point 1 at the under side of the endless delivery carrier the web is severed transversely by the cutters 2 and 3 to form a sheet and the control of the sheet is transferred from the grippers on the delivery cylinder to the grippers on the endless de livery carrier at the point where the paths of the two sets of grippers-concide and the said endless delivery carrier grippers will then lead the sheet outwardly along the under side of the delivery carrier at the surface speed of the delivery cylinders. As the sheet reaches a position nearly over its receiving table, the retarding mechanism for that particular delivery is brought into action as the advance side edges of the sheet are released from the endless delivery carrier grippers and the speed of the sheet is thereby reduced as it drops onto its sheet receiving table. In the meantime, the advance edge of the web :5 is fed downwardly through the guides 8 and 9 and is engaged at the point an by the grippers on the other delivery cylinder and the same operation is carried out by its delivery carrier and retarding device.

By causing the grippers on each delivery cylinder and its endless carrier to travel in circular paths eccentric to each other at the inner end of the endless carrier, the grippers on the endless carrier may be caused to travel 'at the same surface speed as the grippers on the delivery cylinder and be brought into coaction with said grippers at one point, i. e., the transfer point, and at all other times be out of the path of said delivery cylinder grippers, and by causing the grippers 'on the endless delivery carrier to engage the side edges of the sheets, no cross bars connecting the side chains of the endless delivery carrier are needed and the grippers on the endless delivery carrier do not travel around the periphery of the delivery cylinder, but leave it free for the unobstructed passage of the web sheets.

By the term delivery cylinder I wish to include any rotary support for the grippers which travel in a circular path for transferring the sheets cut from the main web, to the endless delivery carrier grippers.

It is evident that slight changes might be resorted to in the form, construction and ar- 5 rangement of the'several parts without de-* parting from the spiritand scope of my invention; hence I donot wish to limit my- 1s)elf strictly to the structure herein set forth,

What I claim is 1.
